【Attachable Charms! With Strap Hole】 There's a strap hole on the spine, allowing you to attach your favorite keychains or acrylic stands (acsta). Decorate it cutely with bead straps and arrange it into your own original planner. 【Perfect for Trading Cards and Cheki】 A7 mini 6-hole size, perfect for your palm. It perfectly fits idol trading cards (small cards) and cheki (instant photos), and is a convenient size for taking photos at cafes or carrying around. 【All-Around Transparent Clear】 Both the front and back covers are made of clear material, which makes the contents stand out the most. You can decorate it with stickers or customize it freely by putting your favorite idol's photo on the cover. 【Ready to Use! Includes 10 Refills】 Comes with 10 card-pocket refills. You can store your precious collection as soon as it arrives and protect it from scratches and dirt. 【For Small Gifts and Exchange Mail】 Because it's simple and doesn't have strong preferences, it's also popular for starting your "oshi-katsu" (supporting your favorite idol), as a gift for friends, or as a bonus for exchanging goods.
